Abstract

본 발명은 키폰 시스템의 역호전환 방법에 관한 것으로서, 통화중인가를 판단하여 통화중이 아닌 경우 재시작하는 단계와; 호전환 신호가 입력되지 않았을 때 재시작하는 단계와; 호전환 신호가 입력되었을 때 지저장된 전환번호를 발생하는 단계와; 국선에 연결된 상대방과 호전환된 상대방과 연결을 시도하는 단계와; 화중음이 발생되었는가를 판단하는 단계와; 재차 호전환 신호가 입력되니 않았을 때 재시작하는 단계와; 키폰 전화기 사용자와 호전환을 요구한 국선의 상대방과 재통화하기 위하여 통화중인가를 판단하는 단계로 복귀하는 단계와; 호전환된 상대방이 응답하였는가를 판단하여 응답하지 않았을 경우 재차 호전환 신호가 입력되었는지를 판단하는 단계로 복귀하는 단계를 구비한다. 따라서, 본 발명은 키폰 전화기 사용자가 호전환을 하였을 때 호전환된 상대방이 통화중이거나 호전환된 번호가 정확하게 입력되지 않았을 때, 호전환 신호를 재발생하여 키폰 전화기 사용자와 호전환을 요구한 국선의 통화자가 재차 통화를 연결할 수 있다.The present invention relates to a reverse call transfer method of a key phone system, comprising: determining whether a call is in progress and restarting the call if not in a call; Restarting when the transfer signal is not input; Generating a stored number when the call transfer signal is input; Attempting to connect with the other party connected to the trunk line and the other party transferred; Determining whether or not a loud tone has been generated; Restarting when the transfer signal is not input again; Returning to a step of determining whether the user is busy to re-call with the key-phone telephone user and the other party of the trunk line requesting the transfer; And if it is determined that the transferred party has responded, and returns to the step of determining whether the call transfer signal is input again. Accordingly, the present invention provides a call for a call to a telephone call user and to transfer a call when the transferred party is busy or the transferred number is not input correctly when the user of the telephone phone transfers. The caller can connect the call again.

Claims (1)

키폰 시스템의 역호전환 방법에 있어서 : 키폰 전화기 사용자와 국선의 상대방이 상호간에 통화를 수행하고 있는가를 판단하여 통화중이 아닌 경우 재시작하는 단계와; 상기 단게에서 상기 키폰 전화기 사용자와 국선의 상대방이 통화중인 경우 호전환 신호가 입력되었는가를 판단하여 호전환 신호가 입력되지 않았을 때 재시작하는 단RP와; 상기 단계에서 호전환 신호가 입력되었을 때 기저장된 호전환되는 번호를 발생하는 단계와; 상기 단계에서 호전환되는 번호가 발생되었을 때 국선에 연결된 상대방과 호전환된 통화자와 연결을 시도하는 단계와; 상기 단계에서 국선에 연결된 상대방과 호전환된 통화자간에 연결을 시도한 후 화중음이 발생되었는지를 판단하는 단계와; 상기 단계에서 화중음이 발생되었을 때 재차 호전환 신호가 입력되었는지를 판단하여 호전환 신호가 입력되지 않았을 때 재시작하는 단계와; 상기 단계에서 판단한 결과 호전환 신호가 입력되었을 때 키폰 전화기 사용자와 호전환을 요구한 국선의 상대방과 재통화하기 위하여 통화중인가를 판단하는 단계로 복귀하는 단계와; 상기 화중음이 입력되었는가를 판단하는 단계에서 화중음이 입력되지 않았을 때 호전환된 상대방이 응답하였는가를 판단하여, 호전환된 상대방이 응답하지 않았을 경우 호전환 신호가 입력되었는지를 판단하는 단계로 복귀하는 단계를 구비하는 키폰 시스템의 역호전환 방법.A reverse call transfer method of a key phone system, the method comprising: determining whether a key phone user and a counterpart of a CO line are mutually performing a call and restarting the call if not in a call; A step RP for restarting when the call transfer signal is not input by judging whether a call transfer signal is input when the key-phone telephone user and the other party of the CO line are busy in the step; Generating a prestored number to be transferred when the transfer signal is input in the step; Attempting to connect with the other party connected to the trunk line and the transferred caller when the number to be transferred is generated in the step; Determining whether a call tone is generated after attempting a connection between the other party connected to the CO line and the transferred caller; Determining whether the transfer signal is input again when a call tone is generated in the above step and restarting when the transfer signal is not input; Returning to the step of determining whether a call is in progress to re-call with the key-phone telephone user and the other party of the trunk line requesting the transfer when the call transfer signal is input as a result determined in the step; In the step of determining whether the call tone has been input, it is determined whether the transferred party responds when the call tone is not input, and when the transferred party does not respond, the process returns to the step of determining whether the transfer signal is input. Reverse call transfer method of the key phone system comprising the step of. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
